Answer

No, the infinite geometric series does not have a limit.

Work Step by Step

The provided series is $2+3+\frac{9}{2}+\cdots $. Here, ${{a}_{1}}=2$, $n=\infty $ and $r=\frac{3}{2}$ Since $\left| r \right|$ is not less than 1, ${{S}_{\infty }}$doesn’t exist. Thus, the infinite geometric series $3+15+75+\cdots $ does not have a limit.
